List of all data types in C programming

In the series of learning programming, we learned about data types. Data type is a system for defining various properties of data stored in memory. Properties such as, type of data, range of data, bytes occupied etc.

Data type in C programming is categorized three categories.

  1. Primitive data type
  2. Derived data type
  3. User defined type
